Unfortunately, our beloved cats can face many ailments that develop as they age. Chronic renal disease is among the more serious of age-related conditions. It affects many older cats, but acute renal failure can be caused by other factors such as eating or drinking toxins, or kidney infection.

Urethral obstruction (UO) is a relatively common medical condition in male cats that usually requires emergency treatment (see related article on page 3 of this issue). Standard treatment - which involves medical stabilization of cardiovascular and metabolic derangements, correction of electrolyte abnormalities with IV fluid administration, and relief of the obstruction by urethral catheterization - may require a number of days in the hospital at considerable expense. The study ("A protocol for managing urethral obstruction in male cats without urethral catheterization," Journal of the American Veterinary Medical Association, 2010) involved a clinical trial involving 15 male cats with UO where standard treatment had been declined by owners due to cost issues.

While youre watching your favorite television show in the family room, you hear a familiar retching sound from the kitchen. Boomer is vomiting up his dinner again. As you clean up the mess, you wonder if its just hair balls - or something more serious that requires a trip to the veterinarians office. Cats vomit for numerous reasons, ranging from benign dietary indiscretion to potentially fatal systemic diseases such as renal failure or hyperthyroidism. The experts say that cat owners should pay close attention to a cat that becomes sick to his or her stomach.

Chronic renal failure is a progressive, irreversible disease that slowly leads to impaired kidney function and serious consequences. The kidneys contain nephrons which are responsible for filtering the blood, removing waste products and regulating electrolytes. In CRF, the nephrons die, and waste products begin to accumulate in the body. Electrolytes may become imbalanced in CRF, leading to problems such as hypertension, seizures, muscle weakness and heart problems.

When a cat begins soiling the house, it is usually assumed that it is a behavioral problem or the onset of senility. However, there are several medical conditions that can cause urinary incontinence and inappropriate urination, some of which require immediate treatment. First, it is important to distinguish between incontinence and inappropriate urination. True incontinence occurs when a cat does not have voluntary control over urination; trauma, a weak primary sphincter muscle and congenital abnormalities are the most common causes of incontinence.

Japans "cat island" - known formally as Tashirojima - was found to be relatively intact after Marchs devasting 9-magnitude earthquake and resulting tsunami, according to Japan Earthquake Animal Rescue and Support. The small island is home to at least 100 people - mostly elderly - and many more cats. The animals are valued by the residents for their beauty, companionship and ability to keep the rodent population down in this fishing area.

Blood can be the gift of life not just for us, but also for our cats. "A cat suffering severe injury or trauma may require blood transfusions," says Marjory Brooks, DVM, associate director of the coagulation section at Cornell Universitys Animal Health Diagnostic Laboratory. Other indications for transfusion include surgical complications and anemia caused by autoimmune disease, renal failure, chemotherapy, parasites in the intestinal tract or fleas. "Young kittens are especially at risk for blood-loss anemia caused by flea infestation," says Dr. Brooks. Cats that need plasma proteins to combat liver disease, clotting problems or rat poisoning may also require a transfusion.

According to a recent Ohio State University, our pets can get sick from stress - just like us. The study found that otherwise healthy cats show signs of illness when stressed. And cats diagnosed with feline interstitial cystitis (FIC) became healthier when stress levels were reduced, the study showed. Twelve of the 32 cats in the three-year study were healthy, while 20 had FIC, a chronic pain syndrome that affects the cats bladder. According to researchers, lower urinary tract diseases occur in about 1.5 percent of house cats, and many pet owners cant tolerate the mess that accompanies it. As a result, millions of sick cats are put down or relinquished to shelters every year.

Your cats eyes, like yours, are delicate structures made up of various components -the cornea, pupil, iris, lens, retina and so forth - each of which plays a role in enabling the animals keen vision. While the feline eye is generally sturdy and resistant to injuries and disease, a wide variety of disorders, such as glaucoma and cataracts, can impair a cats vision and even, in some cases, lead to blindness. According to Thomas Kern, DVM, an associate professor of ophthalmology at Cornell Universitys College of Veterinary Medicine, the most common of all feline eye disorders is conjunctivitis, an inflammation of the thin mucous membrane (conjunctiva) that lines the inner surface of the eyelids and coats the outer surface of the eyeball.

With the economy struggling, its comforting to know that are plenty of ways to defray the cost of owning a cat without compromising your pets well-being. In fact, some of the most effective strategies can actually benefit your cat. According to Jodi Korich, DVM, former director of Partners in Animal Health at Cornell Universitys College of Veterinary Medicine, "One of the best ways to save money on your pets health is to pay attention to early disease detection and preventive health care." Just like oil changes and preventive maintenance result in fewer repair bills for your car, she says, regular check-ups and early intervention will save you money in the long-run.

Researchers studied the effect of distance and neighborhood-level demographics on the number of pet adoptions from an animal shelter ("Use of geospatial neighborhood control locations for epidemiological analysis of community-level pet adoption patterns," American Journal of Veterinary Research, 2010). The methods used to perform the study included client segmentation, geospatial tools, and epidemiological techniques that evaluated locations of 1,563 adoptions from an animal shelter in eastern Massachusetts.

Cat and dog veterinary visits have been declining over the past several years, and a new study might explain why. According to the Bayer Veterinary Care Usage Study, the reasons include: the economic impact of the recession, fragmentation of veterinary services, consumers substituting Internet research for office visits, cat resistance to vet visits, perception among pet owners that regular medical check-ups are unnecessary and the cost of care.
